Between the initial conception of the series and its publication, a large number of details were changed or removed such as: Cordelia and Alastair are no longer white, Charlotte and Henry don't have young daughters, a baby was supposed to need adopting, the ending was originally much more tragic, and even the character's personalities were different.

They were released online to be read for free each month leading up to the release of Chain of Gold.

Cassandra Clare released ten short stories ( vignettes) revolving around the characters from The Last Hours, including Matthew Fairchild, Thomas Lightwood, James Herondale, Lucie Herondale, Cordelia Carstairs, Anna Lightwood, and more.

The series was originally set to be released alternately with The Dark Artifices, before Chain of Gold was delayed until after The Dark Artifices finale.

According to Cassandra Clare: 'The books will interconnect with The Dark Artifices trilogy as two separate trilogies that are also the stories of the Blackthorns, Herondales and Carstairs, much like The Mortal Instruments and The Infernal Devices interconnected despite taking place in different time periods and locations.' The story is also meant to connect in some way with The Wicked Powers series specifically.

The series and book titles were taken from the Charles Dickens' classic novel Great Expectations, of which the series is a loose form of retelling (with there being parallels among characters: James like Pip and Grace as Estella (with many readers assuming that Cordelia is like Biddy in the situation), Matthew like Herbert, and Tatiana as Miss Havisham).Chain of Gold, Chain of Iron, and Chain of Thorns are all narrated by Finty Williams.
